This project amazes me, I did not think that one could create a powerbank for this much! Have you looked in to cost of a pure sine wave converter for to to be a "healthier" current for devices? Or does that make the cost balloon out of control?
My favourite is this one: www.cellsupply.co.uk/bms/daly-3s-12v-30a-bms the issue being that you cant get them without paying for a larger order. this one off amazon(www.amazon.co.uk/Ouitble-Lithium-Battery-Protection-Charging/dp/B09XV8RQKK?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A2HD2RU644B7TL) is a good cheap alternative but it has no short circuit protection so I would recommend using another form of over current protection. another good option is to step up to 4s so that the current is lower, in which case both theses options come in a 4s config as well
Very nice project! Does the $50 (or is it pounds) include the cost of the battery? Also of note would be the Allpowers does have a true sine wave inverter, where your project appears to have a square wave inverter (which is better than the standard crappy wave PWM inverter in the really cheap products). Also, your ground wire coming out of the battery seems to be pretty small. Thanks for sharing!
Thabks Price includes battery, but I have wholesale account so I'm paying around $1.3 per cell. As for the inverter while mine was squarewave, the seller did advertise thr new inverter as sinewave, but I'm not sure of I trust them, I'll test it with a scope and get back to you. Also I'm using 8g wires all round so should be enough.
can you make one out of old vape batteries and show how to do it safe?
lots of people have done it but no tutorials
@MaskedMageYT yeah ill do that this week. Not necessarily as big, as I don't know how many vape batteries I can get.
Just made a tutorial
Absolutely killer video. Thanks, I’ve been wanting to try my hand at this and you’ve helped me a ton.
cool project!
absolutely legendary video, also explained very well
Thanks
Well done .. new subscriber here

Actually trustworthy inverters often cost a lot, but the seller claims this is a pure sine wave inverter, I'll measure and make a short
@@Boris_Woodwards Thank you! You once again are democratizing a lot of cool technologies for a broad range of people who cant afford it!
Great video, thanks. Inverter and charger ordered! Can you recommend a BMS product for this project please?
Depends very much on your location, what country are you in?
@@Boris_Woodwards Sorry, of course. I'm in England.
